Below are notes about some of the TODOs handled.
* In Simulator::Debug:
We haven't had issues with printing in the debugger for a while. If the
feature turns out to be still lacking an issue can be raised.
* In SubStringStub::Generate:
There is no need to jump there. The StringCharAtGenerator is asked to set
the result in x0, and the return sequence following only uses two instructions.
Also, we would need to jump after the native counter increment instead of the
return_x0 label.
* In ArrayPushStub::Generate:
Raised an internal issue to check and update the ARM code.
* In MacroAssembler::CopyBytes:
The new code should be faster for bulk copies. Raised an internal issue to
investigate and improve this function.
* In MacroAssembler::EnterExitFrame:
Unless we actually find something is wrong, this is working and looks ok.
Also fixed the comments about the FP registers.
* Comment for BumpSystemStackPointer:
Removed the comment at the declaration site and updated the TODO in the

the only function printing stack traces was V8_Fatal, but that also terminated

A64: Fixes for the veneers emission.
This patch includes 3 fixes for veneers emission.
1) Block veneer pools emission in the PatchingAssembler.
2) Fix the check for veneer pool emission just before a constant pool.
3) Forbid copy of labels. The list of JumpTableEntry used to track the
deoptimization table entries would make copies of the labels when growing.
Doing so, it would confuse the Assembler that was tracking the labels via
pointers.

Speed up A64 simulator by removing useless memcpy.
The addresses involved should always be aligned, so we can simply use
a cast, just like the ARM simulator. Even if the alignment assumption
did not hold and the platform we are running on couldn't handle
unaligned access, some #ifdefs would be much more preferable. The
affected member functions were the top 2 in a profile (18% and 15%),
so basically every hack is allowed here to speed things up. :-)
Removed some dead code for literals on the way. If we need to
resurrect it, we should do it without double(!) memcpys.
Generally, I still don't understand why we need the Instr/Instruction
distinction or simply wrap Instr within Instruction, this seems to
be much simpler and cleaner, but this would involve heavier changes.
The overall speedup of this CL is roughly 37%, see the numbers below
for a reduced Octane suite and the check targets:
